Difference between embryo transfer and test tube baby
Embryo transfer and test tube baby are two common methods of modern medical technology in the field of assisted reproduction. Although embryo transfer and test tube baby are both means to deal with infertility, there are some differences in operation mode, success rate and applicable objects.
1. Different operation modes
Embryo transfer is to transfer the fertilized embryo into the female uterus to complete the process of pregnancy and pregnancy. The common embryo transfer methods are intrauterine insemination (AIH) and in vitro fertilization (IVF). Intrauterine insemination is to transfer the fertilized egg into the uterus directly through the cervical passage, while in vitro fertilization is to transfer the fertilized egg into the uterus in the laboratory.
IVF is to select the best quality embryos for transfer after the fertilized eggs are cultured in vitro. In the process of IVF, women will receive a series of ovulation promoting drugs to obtain multiple mature eggs for fertilization. After in vitro fertilization and culture, the obtained embryos will develop in the laboratory environment to the stage suitable for transplantation, and then be transplanted back to the uterus of women, waiting for the success of pregnancy.
2. Difference in success rate
There are some differences in the success rate of embryo transfer and IVF. According to statistical data, the success rate of embryo transfer is usually between 30% and 50%, and the specific success rate will be affected by many factors, such as female age, endometrial status, etc. The success rate of IVF is relatively high, usually between 50% and 70%, which is relatively easier to achieve certain success than embryo transfer.
3. Different application objects
Embryo transfer is applicable to women who have successfully fertilized and have normal embryos. This method is often used for couples who have experienced infertility but no other fertility problems. Especially after in vitro fertilization, if multiple normal embryos are formed, one or more embryos can be transferred to increase the pregnancy success rate.
IVF is suitable for couples who have serious infertility problems caused by multiple factors. Women who cannot conceive naturally can get the chance to conceive through IVF technology. In addition, IVF can also be used for selective embryo screening to avoid the transfer of embryos carrying certain genetic diseases.
4. Selection of clinical hospitals
Embryo transfer and test tube baby should be carried out under the inspection and guidance of the clinical hospital. In China, common embryo transfer and IVF technologies can be obtained in large general hospitals and professional reproductive medical centers. For example, the Reproductive Medicine Center of Peking Union Medical College Hospital and the Reproductive Medicine Center of Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine both provide services of these two technologies.
Summary
Embryo transfer and test tube baby are two common methods to deal with infertility. Embryo transfer realizes pregnancy by transferring the fertilized eggs into the uterus, while IVF selects the best quality embryos for intrauterine transfer after cultivating the fertilized eggs in vitro. They are different in operation mode, success rate and applicable objects. Moreover, through the selection of clinical hospitals, patients can get professional technical guidance and help to improve the success rate of treatment.
